Well, it was okay, but...
Let me get one thing clear first: I like this work, and I think this has potential as a series.
Regarding the artwork, considering you only used a mouse, you did pretty good. However, my biggest beef with this movie is pacing and audio. On pacing, the dramatic moments took too long at times, especially at the begining. And this movie would benefit immensly from soundbytes and dialogue. yeah, it's not easy to get quality soundbytes, but it's just my opinion...
Storywise, you've got something here. Really.
All in all, I will wait for part 2 (and 3 and 4 and 5...)
